ARP Bolts M10 Black Chamfer Washers 0.850in OD Chromoly 10 Pack - 200-8592

If you're diving into some serious Jeep upgrades or just need to tighten up a few things under the hood, these ARP M10 black chamfer washers are worth a look. I’ve had my fair share of experiences with various washers, but these ones really stand out. First off, they’ve got that perfect outside diameter of 0.850 inches (or 21.590 mm for those who prefer metric), which fits snugly in a variety of applications.

The inside diameter is 0.394 inches (10.007 mm), and let me tell you, that’s just right for M10 bolts. You want something that’s not going to slip or wear out easily, and these washers deliver. With a thickness of 0.120 inches (3.048 mm), they strike a nice balance between strength and flexibility.

Made from chromoly, these washers are tough as nails. The black oxide finish not only looks sleek but also helps with corrosion resistance, which is a big deal if you’re taking your ride off the beaten path. And no, there’s no inside diameter chamfer—these are designed for direct, solid contact.

What’s really nice is that they’re hardened, so you know they can take a beating. Whether you're tackling a heavy-duty project or just need reliable hardware for routine maintenance, these washers won’t let you down. Plus, they come in a set of 10, so you’ll have plenty on hand for multiple jobs or future upgrades.

In short, if you’re looking for a solid, dependable washer that won’t back down from a challenge, grab a pack of these ARP chamfer washers. Trust me, your Jeep will thank you later.

The Story Behind ARP Bolts

ARP (Automotive Racing Products) was founded by Gary Holzapfel in 1968 when he noticed his drag-racing friends succumbing to bolt-induced engine failure as a result of poor-quality fasteners. He drew upon his expertise in the aerospace industry to develop a solution, which turned into a successful business nonetheless. 

Since its inception, ARP has been engineering and perfecting a wide range of bolts, studs, nuts, and other fasteners for engines, cylinder heads, headers, wheels, and transmissions. Today, ARP remains the undisputed world leader in automotive fasteners. Racing aficionados everywhere know and recognize the ARP brand and can vouch for its quality.

What Makes ARP Bolts So Special?

Located in Ventura, California, all ARP processes from raw wire to finished fasteners are conducted in-house, right here in the USA. The company continually improves its processes with strict quality control guidelines and is dedicated to producing products that are second to none. Simply put, ARP Bolts are better than the competition because of their quality materials and advanced processes. 

ARP prides itself on using only top-quality materials that are above the usual “aerospace-grade” quality that other manufacturers settle for. For example, while 8740 Chromoly steel has four different grades, ARP only uses the top two, SDF and CHQ. These grades cost twice as much as the lower commercial and aircraft grades, but deliver “zero defect” quality that you can trust each and every time.

ARP Bolts are built to withstand serious racing, possess greater tensile strengths, and can survive higher stress levels than most aircraft fasteners. ARP is dedicated to creating fasteners that boast ultimate strength and durability to ensure they last race after race. Its product lineup ranges from quality high-performance OEM parts to exotic specialty hardware for IndyCar, NASCAR, NHRA drag racing, Formula 1, and even marine applications.
